Regarding the katana whatnot

[eestikaa]

Well i was planning to start using a katana as my main weapon but i sold it accidentally. Now i need to make another one. What would i need to make the 1500 credit iron katana shown in the crafting menu? I could not see the materials there. If possible, a way to obtain those materials would also be appreciated.
EDIT : I can provide a picture of the materials needed, but i cannot type Korean...

The second material on the list is in such great need for me. If i had like 20 pieces of it, i could complete my armor set ;O

All iron versions of the weapons can be bought from the girl to the right side of the smith. It only costs zeni. Usually amounts to 2k at most, and is preferable than creating from scratch (only make bone ones from scratch).

I did not see this weapon in the merchant. All he sold were 2 greatswords, but no (iron) longswords.
